First New 30 Rock Promo Raises the Question: What Is Liz Lemon's Secret?

30 Rock‘s sixth season is right around the corner (premiering Thursday, Jan. 12 at 8/7c), and with it comes everyone’s fave, Liz Lemon, who is — according to this just-released promo — harboring a big ol’ (or is it baby-sized?) secret.

A li’l Lemon is of course our guess, but also the most obvious one given the fact that the delay of the NBC comedy’s coming season was due to the real-life pregnancy of Tina Fey, plus Liz has been longing to have kids of her own over the past few seasons. And this new footage actually seems to support our theory — give or take an appearance by Kelsey Grammer. One final clue: The season premiere is titled, “Hey, Baby, What’s Wrong?”

Whatever it is, “The secret of Liz Lemon will be revealed,” Mister Voiceover Man promises in the promo. So, for now all we can do is sit tight and play the guessing game. Take a peek at the preview below, and then hit the comments with your own “secret” speculations!
